WebJun 19, 2024 · The wave vector is perpendicular to the direction of motion of waves, by definition. Let's say you observe these waves and you'd want to count number of waves per unit length in a particular direction. If you stand on the x -axis, you'd count k x number of waves, and k y if you stand on the y -axis.

WebAug 13, 2007 · The idea is that if Fermi surface contours coincide when shifted along the observed CDW wave vector, then the CDW is considered to be nesting-derived. We show that in most cases this procedure has no predictive power, since Fermi surfaces either do not nest at the right wave vector, or nest more strongly at the wrong vector. ray robson r\\u0026j batteries
